The latter is rigidly secured by means ofV a screw `to the'oscillating shaft il of the nnipper. 'On'said shaft are Yfurther securedby meansoiE screws the levers (Figs. 2 and 6), to which are pivotally con? nected the levers 24, supporting tbe primary comb 25, i VThe oscillating- 'upper `shaft i carries further the rigidly secured lever 2, (Figs. l andV 2) in the -outer'end of which the bolt 6 is mounted. 'On this bolt the rod ,o is 'loosely mounted, the outer end ofwhich `is pivot-ally connected to the shaft 7- ofi-.he nipper. I This -shattf 7 is `mounted in. the upper nipper arm 8 having a bearing 8V" and supports 'rotatably the lower nipper arm 3 which is constructed as a dor-.ble lever by th aid of itsezitension member The upperl nipper arm 8 can oscillate around the shaft wot-the frame G, so that the 'whole nippel" is suspended inl'v such `a Y manneras to-be" freely movable in the chine.

In order toinalreit possible to remove the nipper arm 85 Vits bearing 8 is 'shaped hooklilge according tothe invention', so that the. nipperitself can be suspended trom the shaft l0.i A`'Eothe upper' arm `8" are s'e'curedthe uppe'rjawsS-andto the lower arm the lower -jaws 4l rllhe lower 'armV B'has two urther extensions-Stand 3?. .To-3a is secured the set-and stop-screw 11 and 'tof3his pivotally connected the spring 12 which serves topress together'the jaws t and 9; the othei` end ofV Vsaid springV is pivotally and adjustably coni nected to the lever 2. On the shaftV 13 is mounted the combing drum 14- with the' needle segment 18 andthe carding rail 15.

Below the combing drum 14; (Fig. 6)y the brush 34 is arranged and below said brush is mounted the doffer 35 with the dolfer-coinb V36, while above the combing drum 14 in the known manner theV detaching rollers 1G, 17H

are 'arranged'.V In frontof. the latter the fleece trough 30. thepair of dofling` rollers 31,32and Vthe table 33 are disposed.

VUpon the lower nippel' jaw L1- the' -feeding roller 29 is rotatably disposed and behind the same the pivotally arranged. trough 23 and on the bracket 26 the bobbin rollers 27' arerarranged.' V

j Theupper gaw 9 (Figs. 1,2, 5a) describes during its oscillating, movement tliecircular course DE rand the lower jaw the broken course ABC. Approximately the break'- ing point B the nip'per mouth opens, until the point C is reached.

Y effected in the most simple manner, by lift? The removal of the nipper (Figs. 3, l1) is ing the spring 12` out of the extension 3b and by withdrawing the bolt. By this operation the nipper is entirely released from. any connect-ionA with-the machine and can be removed-at once from its suspension point 10 without necessitating a readjustment, as the nipper remains a homogeneous entirety in itself, andas the screw 11, regulating'the adjustment of the nipper mouth, is not dislocated thereby; The reattachment isachieved by placing the nipper again on the bolt 10, attaching` the spring 12 to the extension Y3" and by inserting the bolt 6, so

' that the nipper immediately assumes its previous position. f

The actuation of the nipper is as follows :lv The shaft 1 Vis oscilla-ted forwardly and rearwardly in the usual manner by means of the eccentric 20, the eccentric rod 21 and the lever 22 around the axis of said shaft, so that the lever 2, mounted on the Vshaft 1, is also caused to oscillate and the bolt 6 which ismounted in the lever 2, describesy the arc between the two points 6 and 6" (Fig. 2). By means of the connection` of therod 5 with the nipper shaft 6 the nipper is also caused to oscillate so that thewhole nipper is oscillating around the suspension point 10. The jaw 9 of the upper arm-8 then describesthe arc DE (Figs 1 and '2) while the jaw 4 lof `the lowerv arm 3, which' jaw is pressed bythe spring 12` against the upper jaw 9 also Imakes this movement in accordance with Vthe rcurve AC (direction of the arrow al), thatis to say', parallel with the arc( DE approximately up v,to the point B, which corresponds to the point, .where this movement the set vscrew 11 ofthe lower arm extension 3L1 engages'with the knob .19 of the dra-w rod 5, and accordingly is Yprevented from the further oscillating movement around thel 'bolt`10 and is deviated fromfthe circular course AB towardsCi; On account of this operation the'ciombed pile tuftof the rolled .\ba`nd, passing from. the bobbin rollers 27 Y p over the trough 28 and between the feeding ,75

roller 29 and the-lower: jaw It or ,between the upper jaw 9- and the lower jaw*tjrespecfV tively comes into the Yreacliof the detaching rollersl, 17a'ndris detached bythe same.'

and is furtherconducted over thetrough 30' by meansof thedoiling rollers 31,32 and finally reaches the table33 in theform `of web. The longer or shorter fibers combedout 'from the pile tuft bymean's'of V thecomb- Y -to further-'oscillateforwardly (direction of the arrow d). 'Accordingly the nipper pro ceeds` slowly in the same direction as the the l nippel' respetar; i

combing drum 111, which rotates. in the direction of thearrow c. When' the nippermouth has reached the point B, allneedles have passed through `the tuft. Meanwhile theY stopfand setascrew 11 has descended on the knob 19 of the rod 5 and in vtheffurther oscillating moment, after having reached lpoint B presses on thisrod and prevents thereby the lower `jaw tfiom .participating inthe circular movement around ,the'bolt 10.

As accordingly the upper jaw 9V maintains A (DE), the vnipper .mouth opens from 'BC, sotliat' the Vfree hanging tuft is conducted /tov 4the pair Yof detaching vrollers 16/'17 and is slowly detached by the same (Figs..2and 5) at the same time the spring 2 is somewhat relaxed.

That during this operationthe not shown 4 primary comb enters between thel-nipper and detacliing rollers and performs a subsequent combing .operation :is known andfis of no -importancejto this inventionf iin When the `detaching operation is finished i the nipper oscillates rearwardly in the di rectioii of 'the ,arrow a, and closes at' the point B, as fthe screw '11 'disengage's from the knob 10 andthe Espring '12cont'rsactsagain after the new 'tuft lh'asbeenadvancedby means ofthe` (notjsliownffeeding device, whichlatter;does inot form. a partof the subject ymatter `.ofthis invention; Th'is tut is clamped andlslowlyrbroughtiinto reach of the meanwhile arrivingiirstgneedles .of .i

Y from-which pointA all operations are repeated.

Incase, the needles'of the "nippei-are damaged in some way, the nipper can be easily and quickly removedfroin'theV ina-v chine as a whole in accordance with the invention and/eventually damaged needles can fie be straightened within the "machine-con-v trary tothe previous construction, in which theV combing segment had to Abe removed. Further it is not necessary tochange thead# justinent ofthe nipperV mouth.V
